LEGO’s Pick a Brick service is no longer shipping most pieces to the US due to Donald Trump’s tariff policy. Pick a Brick allows people to buy individual bricks for prices that are usually less than a dollar each. But due to the elimination of the de minimis policy, which waived tariffs on imports less than $800, it is no longer financially viable for LEGO to ship to the US. Some bricks are still available, as LEGO keeps popular bricks in warehouses in the US, but most bricks are shipped from Denmark. Canada, for unknown reasons, is also affected by the shipment pause.
When trump said you need less dolls, he meant minifigs.
